Python TypeError，send_mail（）缺少1个必需的位置参数：'；收件人名单'；

我添加了一个布尔值，因此属性标题在前端是不可更改的，但是我得到了这个错误

TypeError at /contacts/contact
send_mail() missing 1 required positional argument: 'recipient_list'
Request Method: POST
Request URL:    http://127.0.0.1:8000/contacts/contact
Django Version: 3.0.4
Exception Type: TypeError
Exception Value:    
send_mail() missing 1 required positional argument: 'recipient_list'

views.py

def contact(request):
        if request.method == 'POST':
            property_id = request.POST['property_id']
            if 'property' in request.POST:
                property = request.POST['property']
            else:
                property = False

            name = request.POST['name']
            email = request.POST['email']
            message = request.POST['message']
            realtor_email = request.POST['realtor_email']

            contact = Contact(property=property, property_id=property_id, name=name, message=message )

            contact.save()

            # Send Email
            send_mail(
                'Property Inquiry',
                'There has been an inquiry for' + property + 'Check it',
                ['m@gmail.com', 'j@gmail.com'],
                fail_silently=False
            )

设置.py

EMAIL_HOST = 'smtp.gmail.com'
EMAIL_HOST_USER = '******@gmail.com'
EMAIL_HOST_PASSWORD = '*****'
EMAIL_PORT = 587
EMAIL_USE_TLS = True

更新： 这段代码成功了

'There has been an inquiry for' + str(property) + 'Check it',

---

发送邮件功能中缺少一个

，

，希望对您有所帮助。

请提供一个，以及整个错误消息。

“属性查询”后缺少一个逗号。

当您想将str与布尔值连接时，您也应该将布尔值转换为str，就像

“已对”+str（属性）进行查询一样+“Check it”

当我尝试将布尔值转换为str时，我得到一个“send\u mail（）缺少1个必需的位置参数：”recipient\u list“错误
